Question

我已经编写了一个查询工具，该工具的核心使用此块从外部网址收集信息：

AsyncHttpClientConfig proxiedCF = new DefaultAsyncHttpClientConfig.Builder().setUserAgent(pickUserAgent()).build();
AsyncHttpClient asyncHttpClient = new DefaultAsyncHttpClient(proxiedCF);
Future<Response> f = asyncHttpClient.prepareGet(url).setProxyServer(new ProxyServer.Builder(pickProxyServer(), 80)).execute();

工作正常。但是，即使提供了无效的代理，它仍然有效，这有点可疑，我觉得我的精心设计的代理配置根本就没用过。

我偶然发现pickProxyServer（）返回一个String＆＃34; 1.1.1.1＆＃34;，这显然不是一个有效的Web代理。

我使用SLF4J进行日志记录，看起来很正常：

20:31:47.454 [AsyncHttpClient-7-1] DEBUG o.a.n.channel.NettyConnectListener - Using new Channel '[id: 0x03359938, L:/10.0.0.101:59775 - R:/1.1.1.1:80]' for 'GET' to '[[url removed by me]]'

有人能指出我的错误吗？显然，当调用无效代理时，我想要一个I / O异常或任何类型的通知。

Answer 1

好吧，半夜，但我找到了一些东西。当端口不是：80时，代理正确使用。这对我有用。

AsyncHttpClient不使用提供的代理数据
